In the embodiment of the invention shown in Figs. 1 and F8: the fabric is given consists of e strip of metal perforated atintervels n 26 and in each perforation 26 is arranged 2. leg 18 of one unit and a. link 27, one end of the link being connected with an adjacent un-' occupied loo 20 of an appropriate unit; The ends of this band are secured in the frame by 'hehcal, springs 28 which are positioned like and resemble in all respects the helical springs 13.

In Flg. 4. the fabric 1s shown as provided with a link edge instead of a band edge as shown in F i s. l and 2. Thisedge is pro-- vided by making the oul'er legs 31 of the links, which are located at the edge of the fabric, much longer than inner legs 32 and much longer also then the legs 33 of the units forming the'body of the fabric. It will be noted by viewing Fig. i that only every other row disposes a unit at the edge of the fabric and the legs 31 are made of suffi ient length to engage the loop 35 of the next link at the edge of the fabric. The legs 31 are disposed substantially in a straight line and give the fabric a smooth even edge. A similar elongation or" a leg 3'? of the fastening member h; is

)rovided to ene'a e the loo) 35 of the ed" il l jaccnt edge unit 2?). The body portion of the tcbric shown in this figure and the means oi iustening 1* 1D. piece are identical l l l l A with that of the embodiment shown in Figs. 1 and ,2 and detailed description thereof is not thought to be necessary. I

It will be noted in viewing Figs. 1 and 4: that the units when assembled provide a plurality of diamond shaped openings, each hounded-on two sides by a pair of. legs of a rel-genes Will widen or narrow the fabric as desired and these variations in width will not increase or diminish the number of springs required to fasten such fabric in place, it only being necessary that the eyes in the frame be appropriately positioned. The number of units in each row may be varied without altering-the-Widt; of the fabric and such nriations will necessarily be accompanied by an altered number of springs; The errangomentct the adjacent endsof the diverging legs of each unit permite the changes the fshriohereinhefore suggested to be accomplished'without affecting appreciably the strength or durability of the finished spring byreeson of the fact thzitthe legs maydiverge any desired :rinount without imposing upon the Wire or other material forming the units any undue strain'et the juncture of the legs. it will'loe zipper-ant also that the portions :21 beneath the legs and eonnectingthe loops act as tension members when the fabric. is in use and thereby materially strengthen the febnio transversely and. prevent in large degree distortion of the links when a weight is suddenly applied to the spring' 'IiIWlll be halt diamond link type, comprising a plurclity of intcrengaged units ouchco'gnprising a pair of diverging legs connected at their adjacent cnds'ton pair oi outwardly extending: rind coiled loops connected by a bar, the
